PURPOSE: Structure of a washer liquid spray nozzle for a vehicle is provided to enhance the washing effect of a front glass by varying the spray intensity of a washer liquid depending on a vehicle speed. CONSTITUTION: A control unit(13) to control the opening degree of a nozzle body(10) is installed on the nozzle body connected with a wash liquid supply pipe(20). The control unit consists of a plunger(14) and a spring(15) to offer elasticity to the plunger. The spring maintains the open state of a path(11) via the plunger. If the plunger is closed in a large degree due to excessive pressure difference between the front portion and the rear portion of the nozzle body, a washer liquid is sprayed at a high speed. If the pressure difference is low, the washer liquid is sprayed at a low speed. |
